This paper proposes a torque control method for interior permanent magnetic synchronous motors (IPMSMs). The proposed method controls the voltage amplitude and phase based on a new n – t coordinate system. The t ‐axis is a tangent line of a constant voltage ellipse, and the n ‐axis is a normal line of the ellipse. On the n – t coordinate system, the n ‐axis current is not affected by the voltage phase. The n ‐axis current is utilized to reduce the mutual coupling between the voltage amplitude controller and phase controller. The proposed method realizes a high torque response for the linear range and overmodulation range of the inverter, including six‐step mode. The effectiveness of the proposed method was verified by simulation and experimental results.
